MetabolomicsNeuronal tRNA modifications in Aplysia californica are repatterned during behavioral habituation
Transfer RNA (tRNA) modifications have been increasingly implicated as post-transcriptional regulators of basic neuronal functions. However, characterizing tRNA modification profiles in specific neural circuits that control well-defined behaviors is notoriously difficult due to the complexity of con...

TranscriptomicstRNA Over-Expression in Breast Cancer
Increased proliferation and elevated levels of protein synthesis are characteristic of transformed and tumor cells. Though components of the translation machinery are often misregulated in cancers, how tRNA plays a role in cancer cells has not been explored. We compare genome-wide tRNA expression in...

TranscriptomicsA growth-essential Tetrahymena Piwi protein carries tRNA fragment cargo
Argonaute/Piwi proteins associate with small RNAs that typically provide sequence specificity for RNP function in gene and genome regulation. Here we show that Twi12, a Tetrahymena Piwi protein essential for growth, is loaded with mature tRNA fragments. The tightly bound ~18-22 nt tRNA 3M-bM-^@M-^Y ...

TranscriptomicstRNA fragment profiling in CLP1 mutant (kinase-dead) mice
Loss of CLP1 activity results in the accumulation of novel sets of small RNA fragments derived from aberrant processing of tyrosine pre-tRNA. Such tRNA fragments sensitize cells to oxidative stress-induced p53 activation and p53-dependent cell death. 2 samples, Wt and Clp1(k/k), no replicates

TranscriptomicsIdentification of tRNA sequences in Lactococcus lactis
we report the identification and sequences of the tRNAome of industrially relevant microorganism Lactococcus lactis Three Next Generation sequencing runs annotated as S1, S2 and S3 were performed. Cells were harvested at exponential phase and tRNA was isolated. S1 and S2 were spiked with Phe-tRNAGAA...

TranscriptomicsThe Translin-TRAX complex/C3PO is a ribonuclease in tRNA processing
The endogenous RNA substrates of Translin-TRAX complexes (also known as C3POs) and how they regulate diverse biological processes remain unknown. Here we show that Translin and TRAX do not play a significant role in RNAi in the filamentous fungus Neurospora crassa. Instead, the Neurospora C3PO compl...

TranscriptomicsBiogenesis and function of tRNA fragments during sperm maturation and fertilization in mammals
Parental dietary conditions can influence the metabolic traits of offspring. In mice, paternal consumption of low protein diet alters cholesterol and lipid metabolism of progeny. Here, we examine RNA species expressed in male reproductive tissues of mice. Protein restriction leads to altered levels ...

TranscriptomicsGenome-Wide Translation Profiling by Ribosome-Bound tRNA Capture
In the ribosome complex, tRNA is a critical element of mRNA translation. We reported a new technology for profiling ribosome-embedded tRNAs and their modifications. With the method, we generated a comprehensive survey of the quanity and quality of intra-ribosomal tRNAs (Ribo-tRNA-seq). Ribo-tRNA-seq...

MetabolomicsVirus-induced codon-specific reprogramming to favor viral RNA translation
Recent evidence indicates that codon usage bias regulates gene expression. How viruses, such as the emerging mosquito-borne Chikungunya virus (CHIKV), express their genomes at high levels despite an enrichment in rare codons remains a puzzling question. Using ribosome footprinting, here we analysed ...
